Auto Configuration
Overview
When an auto configuration is performed, the D77D-EMA assembles the IO data into
input data registers and output data registers for the devices on QCPort channels CHA
and CHB. The data is assembled by QCPort channel and then in ascending order by
device Group ID (address switch setting on device) using the default IO assembly for
each device. For further assistance on the IO size and how data is mapped within the
registers, refer to the user manual for that device or refer to CH Studio for on-line help.
Once the QCPort system is assembled, powered and properly addressed, one of two
types of auto configuration can be performed. The procedure for performing a Soft
Configuration or Hard Configuration starts on
Page 26
. No additional configuration of the
D77D-EMA is required for normal operation.
Notice
Use CH Studio when it is necessary to configure enhanced features
Preparation
Prior to performing an auto configuration procedure, take the following steps to ensure a
properly assembled system.
•
Verify that all QCPort devices are set to a unique Group ID (QCPort address). For Group
ID settings above the Group ID switch range, CH Studio is required.
•
Verify the sizing of the power supply.
•
Check that QCPort is properly wired and properly terminated.
•
Refer to MN05001002E
(QCPort System Installation and Planning Guid
e) for further
information on QCPort System design.
When the system is powered properly and Modbus is connected properly, the status
